Choppy Preview... will updating to PD12 help?

I have a terrible preview that rarely plays back smooth, freezes then jumps ahead during playback. It makes trying to edit like pulling teeth. I've done all I've found recommended in here, including all the steps I took on a past post a couple of years ago when I was having the same problem. For the last couple years it's not been that big a deal, since I wasn't trying to put together many clips and sync them with music to make another film...but now I'm working on my 2nd film and it's taking so long because of no smooth playback.

I'm wondering if I update to PD 12 from my version 11 it will help? I'm just not sure because in my search it seems many have had this problem with 12 too. I'm lost as to what to do.

I'm thinking of editing each clip and producing them independantly, and then putting together all the pre edited produced clips. If I did this, what format should I use that will retain the best resolution when I then produce the finished product. I'm don't want them further compressed since I will already be compressing them once...does this make sense?

Here's the specs of my computer... it's a bit long in the tooth for a computer but it's still going pretty strong...

You don't outline specifics...

If you decide on interim steps, use a file type that closely matches that of the original material.

Reduce PD preview mode, using the icon that is just to the left of the "speaker" - under the preview window.

While editing, shut down all unnecessary programs.

Under the EDIT|PREFS|GENERAL menu, try both the On and Off settings for Shadow Files. (Enable HD Video Processing)

Under the HARDWARE ACCELERATION tab, do the same - testing both On and Off modes for each item.

Similarly, test disabling various AMD Catalyst features, using their software.

Upgrading to PD 12 likely won't solve the problem, IMO, but you can test the trial version...

Thanks Borgus... I have already tried most all that you said, and none have worked. The only thing I haven't tried was disabling various AMD Catalyst features, using their software. I don't know how to go about doing that? Dustie

Sorry, don't use AMD. But if it's anything like NVidia there may be an AMD or Catalyst icon in Control Panel, with various settings that you can test.

Someone else may chime in.

Thanks. I'll do some reading on it and see if I can't test some of the settings. It's something to try anyway.
